About Realtime SDK
Real-time collaboration infrastructure for every development team.
Our Mission
We believe real-time collaboration should be accessible to every development team, not just those with the resources to build it from scratch.
Our Story
Realtime SDK was born out of frustration. We spent years building collaborative applications and kept running into the same problems: existing solutions were either too expensive with unpredictable MAU-based pricing, too complex to integrate, or locked you into a vendor with no path to self-hosting.
We knew there had to be a better way. A solution that gives developers the tools they need without the surprises — built on standard protocols, with pricing that scales predictably, and an architecture that lets you own your infrastructure when you're ready.
Our Values
Developer First
APIs designed for developer experience, comprehensive documentation, and TypeScript-native from day one.
Predictable Pricing
Concurrent connections, not MAU surprises. Know your costs before you ship. No hidden fees.
Open Architecture
Self-host when you are ready. No vendor lock-in. Standard protocols. Your data, your infrastructure.
The Team
Built by a small team passionate about developer tools.
We're growing and always looking for people who share our mission. If you're passionate about real-time systems and developer experience, we'd love to hear from you.
